Goalless at the break, Kevin Stewart then netted twice, with Kamil Grosicki also on target as the Tigers picked up only their second win of the Championship campaign to leave Luton shell-shocked.
McCann said: “I thought first half we showed them a little bit too much respect for my liking.
“They had a lot of possession, we didn’t get out to the ball enough, but they didn’t really hurt us, as I thought we were in control in terms of what we were doing, we just didn’t get them against them enough.
“Second half we showed a different side to us in terms of what we’ve showing this season with high energy, high pressing, breaking quickly, creating opportunities.
“In the end, we probably could have had four or five.”
After a totally uneventful opening 45 minutes, the game came to life after the break.
